First question: You have found a human! What do you do?
The human is committing Genocide.
How do ya hang around your bro?
Ooooh, look, a knife!
If you had to pick, which one of these weapons would you fight with?
What is your favorite food?
If you had to assume a roll, which would you choose?
So, about that human...
They have disappeared.
Genocide?
So, the human... is about to rese- Alright, here we go!
Just kidding. That genocidal human has been spotted. It is talking to Paps .-.
Ok, now it is approaching you.
Underfell
Underfell
Also known as "Edge," "Fell," and "Edgy Mc My Chemical Romance," (Crayon Queen) Underfell Sans has... a very evil, negative outlook on the world. Considering he comes from Underfell, the land of "Kill or BE killed," he is naturally mean, unpolite, and violent. He does not like his world, though, even though he fits in perfectly.
Underswap
Underswap
Also known as "Blueberry," and "Blue," Underswap Sans has a very adventurous personality, directly matching Papyrus' from the original Undertale. His goals are to get into the Royal Guard, and to do this, he must capture a human. He wears a blue scarf, a "battle body," and LOVES tacos, to the same amount that Paps (Undertale) loves spaghetti.
Aftertale
Aftertale
Also known as "Geno," Aftertale Sans has a rough history. Coming from a Genocide timeline, the only reason that he is still alive is the determination that he injected into himself before fighting the human. This extra determination allowed him to flee his timeline and escape into the Save Screen. He wears a white jacket and slippers, and a large cut runs across his chest. He is a really sad version of Sans, but also crazy, being that he has been through Hell watching the human reset again and again, unable to stop their multiple genocides.
Errortale
Errortale
More commonly called "Error" than anything else, Errortale Sans has been driven insane by the emptiness of his home, the Anti-void, a pure white dimension between the game files. He destroys other AU's, but leaves the original Undertale alone, because of his view on the other AUs as "abomionations" of the game. If he were to realize that he himself were ALSO an AU, he would most likely kill himself right then and there. For his attacks, he uses Gaster Blasters and bones, but mostly uses magic blue strings that shoot from his fingertips. He uses them to control other AU's by grabbing onto their SOULs.
Reapertale
Reapertale
Just call him "Death," or "Reaper." This Sans is from an AU where the characters are the gods of something. Sans just so happens to be the god of Death, killing things just by simply touching something. His main enemy would be Toriel, the goddess of life. Reaper Sans has a very laid-back personality, wearing dark robes that evaporate like smoke near the ends. He usually carries a long scythe, and has his left eye glowing the way Classic's would during a Genocide run.
Storyshift
Storyshift
Mainly known as "King Sans," Storyshift Sans comes from an AU where all the characters have their roles in different parts of the game. For instance, Sans takes Asgore's place, Asgore becomes Royal Scientist, Toriel becomes Captain of the Royal Guard, etc. King Sans is just like Asgore (classic), reluctant to fight, but has to for the good of his people. He wears armor, a long cape, and DOES use Gaster Blasters and bones for his attacks. His personality is his own from the original Undertale, but mixed a little with Asgore's. Like, he still loves his puns. :)
Inktale
Inktale
Also known as Ink, Inktale Sans is the guardian of all of the AU's, protecting them from beings like Errortale Sans. He has a very creative personality, drawing constantly, and carries a giant paintbrush wherever he goes. By painting an object with his brush, he can then make the paint into something that can benefit him in battle, like chains. He hates fighting, but will do it if it means keeping all the AU's safe. He is taller than Sans (classic), wears tennis shoes, and has his classic-blue jacket tied tightly around his waist by the sleeves. He is very friendly, but stays hidden from other AU's, to keep his presence hidden.
Undertale
Undertale
This Sans is the original Sans, the pun master everybody loves. Everybody seems to love him, too, from his laziness, all the way to the fierce fight he puts up at the end of a Genocide run. He wears a blue jacket, is lazy, and there is a theory that he suffers from depression. His attacks include his blue attack, bones, and Gaster Blasters. He loves ketchup and hot dogs, and serves as a sentry in Snowdin, watching out for humans. He is the inspiration to a whole other world of other versions of himself, along with every other character in-game.
